I have recently purchased The Petlab 5lt Urine Stain & Odour Remover. I have tried ever off the shelf product and home made remedy I could get with little to no long term good. After talking to the staff at PetLab they advised me to try their Stain & Odour Remover, which I have and after following their instructions I haven't had any pee to clean up on any of the treated areas in the last four weeks. As a result I will be purchasing their laundry detergent to hopefully complete the circle. I have found no other products that work as well as Pet Lab do, and would have no problems recommending there products to family and friends.Thanks Noel
